I need to add the following 2 points:
The importance of Political Education is that you will at least be able to understand what's going on, what they are doing, why they are doing it and NOT to blame it on yourself, on your skills or on your age. This is typical behaviour among billions of workers. It can be fixed and you can regain your self-confidence, which as others said, it's really important for the next steps you will take.
Secondly, I am sure there are a lot of fellow Monks who are leading human teams. A lot of them are also contributing here on their free time at their own cost, or contributing to opensource efforts which is a sign that not all Managers are the same. I am talking about the general trend, the average. Not the exceptions.
